Abstract
The transformation of temporal, one-point correlation functions into longitudinal spatial and spatio- temporal correlation functions in turbulent flows using a simple statistical convection model is introduced. To illustrate and verify the procedure, experimental data (one- point and two-point) have been obtained with a laser Doppler system from a turbulent, round, free-air jet.
